SPECIFIGATIGN forming part of Letters Patent No. 641,509, dated January 16, 1900.

Application filed August 19, 1899. $erla1 No. 727,767. (No model.)

To aZZ whom it may concern:

lie it known that l, WILLIAM'E. HASKELL, of Philadelphia, in the State of Pennsylvania, have invented certain new and useful Improvements in. Valves, whereof the following is a specification, reference being had to the accompanying drawings.

lily invention relates to a valve adapted to automatically permit the flow of water to a water closet hopper during the use of the latter, and, in its preferred embodiment, my improved valve is arranged to be opened by depression of the seat connected with the closet hopper to be supplied with Water, and closed by the water pressure,Wit-hin the valve, upon release of said seat.

in the accompanying drawings, Fig; 1. isa perspective view of the hopper arid'seahwith a convenient embodiment of my invention applied thereto.

Fig. 2, is a vertical sectional view of the valve shown in Fig. 1.

Figs. 3, and 4:, are plan sectional views of said valve taken respectively on the lines 3,

nd 4-, 4, of Fig. 2.

r 5, is a vertical sectional view of a modified form of said Valve.

in said figures, A, is the hopper, provided with the hinged seat B; and O, is the valve arranged to control the flow of water from the water service pipe D, through the delivery pipe E, to the hopper.

The outer casing O, of the valve 0, has a foot flange 0, for connection to its supporting structure, and isprovided with an inlet d, for connection with the service pipe D, an outlet c,i:or connection with the delivery pipe E,and a waste outlet f, which may remain open as shown, or be connected to the drain or sewer, as desired.

Within the valve casing C, the plunger G, is mounted for vertical reciprocation and, the plunger stem g, is suitably extended to contact with the under side of the hinged seat B, and raise the latter as indicated in Fig. 1, when said plunger G, is in the position shown in. Fig. 2. The plunger G, is provided with two'heads G, G the head G, being arranged to control communication between the inlet 65, and the outlet 6, and the head G being arranged to control the communicationbetween the supply outlet 6, and the waste-outlet f, to

drain the pipe E, etc., and thus obviate the danger of water freezing therein, when the closet is not in use.

The relation of the valve parts is such that when the plunger is in the position shown in Fig. 2, the head G, is raised to contact with the seat G by the pressure of water beneath said head in the chamber 0 the latter being in communication with the pipe D, through the port d; and, the head G is raised to permit the free exit of water from the pipe E, around the reduced portion g ,of the plunger G, through the port j".

Said heads G, and G are conveniently formed of cup leathers; the head G, being secured in position by means of thest-ud screw g, entered through the washer y in threaded engagement with the plunger G. Said screw g, also serves as a stop to limit the downward movement of the plunger G, by contact with the bottom of the chamber C The head G is secured in proper relation with said plunger G, by means of the nut g and washer g, the former being in threaded engagement with the stem of the plunger G.

The operation of my device is as follows:- The seat B, being depressed; the plunger G, is shifted downward until the stud screw g, contacts with the bottom of the chamber C In said position of the parts the head G, be-

ing below the port 1 leading from the inlet d, the water supplied by the pipe D, is permitted to pass to the outlet e, and is delivered through the pipe E, to the hopper A. In said position of the parts any waste of the water through the outlet f, is prevented by the head G which closes the port f.

It is to be noted that the valve maybe maintained open only by downward pressure upon the plunger G,by means of the seat B, or otherwise, the Water pressure in the chamber 0 beneath the head G, being at all times suthcient to uplift said plunger G, and seat 13', and thus close the valve when relieved from said abnormal downward ressure.

When so released the valve clese without said seat GP; and, simultaneously therewith the port f, is opened to permit drainage of the pipe E, etc.

As a result of this arrangement, as will be seen, before the head G reaches its seat, it passes upward through that portion of the casing between the upper edge of the inlet 01 and the seat, making, of course, tight contact with the wall of the casing. V

The water in said space above the head G cannot pass down at the side of said head, but must be elevated by said head against the pressure or weight of the water in the casing below the outlet f. The water above the head G, therefore, acts as a cushion to prevent shock in the contact of the head G with its seat, the cushioning action being supplemented by the cushioning action of the air in the upper end of the casing above the head G in the construction shown in Fig. 5.

In the form of my invention above described, the amount of time required to eifect the automatic closure of the valve when released from the downward pressure of the seat is determined by the difference in pressure above and below the heads G, and G of the plunger G, the rate of closing of this form ofmy valve, is therefore practically constant, and predetermined by the proportion of the parts, however, I find it advantageous to provide means to adjustably regulate the rate of felosin g of the valve, and I have there fore illustrated in Fig. 5, a convenient embodiment of my invention, wherein the port f leading from the chamber 0 which serves as a dash pot for the plunger head G is provided with means to vary its eifective area, convenientlya set-screw H, which is in threaded engagement with the casing O, at h, and serves to obstruct said port f more or less in accordance with its position in said casing.

In the construction shown in said Figure 5 the stem is illustrated as provided with a stu ffing box 0 of usual construction and arrangement.

As will be understood, referring still to Figure 5, the air contained in the chamber 0 being unable to escape through the opening in the upper end of the casing through which the plunger stem extends, and only able to escape by a slow rate through the opening or port-f will act as a'cushion to slightly retard the ascent of the plunger 11 nder the pressure of the water beneath the lower head.

The device H controls the size of the opening or port f with the result that while the structure as a whole can be made of standard size, the apparatus may bysaid device he regulated according to the varying water pressure in the different localitiesin which it may be employed.

In the construction shown in Figure 5 any water which may by accident find access to the chamber C will, of course,run out through the outlet f In. the construction shown in Figure 2 no stuffing box is applied to the stem of the plunger and the opening or portf is shown as of quite large diameter.

In this construction the air will escape quite freely through the large opening f and may also escape through the unpacked opening in the upper end of the casing through which the plunger stem extends.

Vater obtaining entrance by accident to the chamber C in the construction shown in said Figure 2 will by reason of the large size of the opening or port f and its location at: the lower edge of said chamber escape through said opening f and will, therefore, not rise through the opening in the upper end of the casing through which the valve stem extends.

It is to be understood that the device ll shown in Figure 5 as controlling the opening or port f may be applied as the requirements of the trade may demand to any of th ports or openings of the apparatus.

It is to be noted that in bothforms of my invention herein set forth, no springs or similar devices are employed to effect the automatic closure of the valve, but said closure is eiiected solely by the water pressure beneath the plunger G, and that when said plunger is in its closed position, the accidental passage of the water through the valve is not only prevented by the lateral pressuie of the head G, within the casing C, but said head is also directly in contact with the seat G in said casin".

It is obvious that various modifications may be made without departing from the essential features of my invention, and Ithereforc do not desire to limit myself to the precise arrangement and proportion of the parts which I have illustrated.
